func TestEtcdClient ¶

func TestEtcdClient(t testing.TB) (*clientv3.Client, string)

TestEtcdClient connects to the shared etcd instance at etcd:2379 and returns a client along with a random prefix for test isolation. It verifies etcd is reachable with a short timeout so tests fail fast with a clear message when run outside the dev environment.

Cleanup is registered automatically: all keys under the prefix are deleted and the client is closed when the test finishes.
